Tesla to install canopies for a 'solar test house' at its Fremont factory
Tesla has plans for the installation of new tent-like canopies for a “solar test house” at its factory, according to a new building permit issued by the City of Fremont.
Per the description noted in the initial filing, Tesla is seeking “two canopy covers over solar test house” that measure approximately 60′ x 80′ & 60′ x 70′. The structures will be temporary and removed after two months.
While there’s no indication on the purpose for the canopies, CNBC indicates that the canopies are meant to conceal research and development on its solar test house from prying eyes, and protect the project from potential delays due to rains.
Seeing progress in the efforts of Tesla to install more Solarglass rooftops brings it another step closer to mass producing the third version of the solar roof tiles. Likewise, such developments can help Tesla capitalize on California’s new building requirements that require newly-built homes to have solar systems starting next year. The state is the first in the country to require solar panel installations on single-family homes and multi-family structures.
Based on the 2019 Building Energy Standards in California, the solar requirement increases the cost of building a new home by roughly $9,500 but has the potential to save homeowners about $19,000 in energy bills and maintenance costs over 30 years. The Energy Commission estimates that an average home will save around $80 on cooling, heating, and lighting bills. Customers such as Amanda Tobler from the Bay Area echo the possibility that these numbers can be achieved. The Toblers had their Solar Roof tiles installed in March 2018 and enjoys more than enough power for their house and two plug-in vehicles as a result.
Tesla also recently posted job openings that aim to beef up its installation teams in California, Florida, Nevada, and Texas. The company looks to hire licensed electricians, Solarglass roofers, installers to join its operations who will most likely not install just its solar tiles but also help to put up Powerwalls and regular solar panels.
-->As the energy company installs more Solarglass rooftops, it will also create more jobs to fill the needs of its facility in Buffalo, New York and possibly save the company $41.2 million in penalties. Tesla promised to produce its solar panels in the said facility, which used $750 million in taxpayers’ money and the deal requires it to generate around 1,500 jobs by April next year.
Tesla CEO Elon Musk says he sees the company’s energy business to grow as big as its electric vehicle business. In Q3, Tesla deployed 43MW of solar or 48 percent more compared to the previous quarter.
“…the really crazy growth for as far into the future as I can imagine. … It would be difficult to overstate the degree to which Tesla Energy is going to be a major part of Tesla’s activity in the future,” he said during with Wall Street analysts.
Tesla started accepting orders for its V3 Solar Roof in October and Musk revealed that it plans to eventually install 1,000 solar roofs a week. Interested homeowners who want a Solarglass rooftop can use the company’s online configurator to estimate the costs. The estimated pricing for a 2,000 sq. ft. roof with 10kW solar is $33,950 after a federal tax credit of $8,550.
As of 2018, there are only 15 to 20 percent of California single-family houses with solar panels installed according to the estimates of the California Building Industry Association.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
-->The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
